What do you mean by "a negative of our branch"? The idea seems confused to me. Specifically, if the universal wavefunction is a function Psi on config. space, and "our branch" is the portion of the wavefunction whose domain is the config. space region Q, then what is the negative of our branch? Is it -Psi(Q)? Is it Psi(-Q)? In neither of these cases does your point hold, I think. Were you thinking of something else?
